Description

Collaborative scheduling method for integrated sponge urban water storage and drainage system Technical Field The invention relates to the technical field of municipal engineering and water resource management, in particular to a cooperative scheduling method of an integrated sponge urban water storage and drainage system. Background Along with the deep advancement of sponge city construction concepts, the urban water storage and drainage system is transformed from a traditional rapid drainage mode to a seepage, stagnation, storage, purification, use and drainage integrated cooperative regulation and control direction. The integrated sponge urban water storage and drainage system collaborative scheduling method aims at realizing dynamic optimization management of the whole rainfall runoff process by comprehensively planning multiple elements such as the ground surface, a pipe network, a regulation and storage facility, a receiving water body and the like, and improving urban waterlogging prevention and control and water resource utilization efficiency. However, the prior art still has obvious defects in terms of system integration level, scheduling response precision and multi-objective coordination capability. Through searching, a collaborative scheduling method for urban drainage areas is disclosed, with the publication number of CN111798108B, and the method dynamically adjusts the running number and frequency of the water pumps by adjusting the liquid level control value of the pump stations in real time so as to realize active regulation of the pump stations and reduce overflow pollution of areas. However, the technical scheme is mainly focused on the local optimization of the drainage pump station, is not fully incorporated into the source stagnation effect of sponge facilities (such as water permeable pavement, rain garden, green roof and the like), is also lack of coupling modeling of the whole process of surface production confluence, pipe network transmission and terminal emission, is difficult to support the cooperative scheduling of the whole chain of source-process-terminal, and limits the applicability of the system in a complex multi-source system of a sponge city. On the other hand, a scheduling decision method and a scheduling decision system suitable for integrated management of a plant, a network and a river are disclosed, wherein the publication number is CN119047724B, and the patent builds a 'plant-station-network-river' integrated mechanism model covering ground runoff, a pipe network, a river network, a sewage treatment plant and a regulation and storage tank, so that the whole process simulation and collaborative regulation and control of water quantity and water quality are realized. Although the scheme is comprehensive in system coverage, the core of the scheme is surrounding the traditional sewage and combined overflow management, the dynamic response characteristic, the storage-discharge conversion mechanism and the linkage scheduling strategy of gray infrastructure of Low Impact Development (LID) facilities special for sponge cities are not considered enough, and the scheme is not specially designed for the balance optimization of the quick response and multiple targets (waterlogging prevention, water saving and water quality guarantee) under short-duration heavy rainfall events, so that the requirements of high-efficiency and elastic operation of the sponge cities under extreme weather are difficult to meet. The problems show that the prior art is limited to regulation and control of a single facility level, or a wide area model is built but the dynamic characteristics of the sponge facility are not integrated, and an integrated collaborative scheduling method for a full chain of source emission reduction, process control, terminal regulation and water receiving protection is not formed. Therefore, the invention provides a collaborative scheduling method of an integrated sponge city water storage and drainage system, which aims to integrate a dynamic response mechanism of multi-source heterogeneous facilities, construct a high-precision, quick-response and multi-target collaborative intelligent scheduling system and comprehensively improve the toughness and the recycling level of a sponge city under a complex rainfall scene.
